Abstract

Abstract We developed an index of vulnerability for odonates (IVO) that occurred predominantly in Mexico to assess land use change. Vulnerability was defined as a function of A) habits of the species and B) ecological niche models. Index validation was done by relating it to rate of vegetation cover change, with the habitat preferences of each species and with species’ sensitivity to habitat deterioration. Thus, the most sensitive species would be found in areas with no change in land use. IVO values ranged from a maximum of three (i.e., the most sensitive) to a minimum of one (i.e., the least sensitive). As it was demonstrated in other studies, odonates did not show a clear preference between conserved and perturbed land uses. Interestingly, the few sensitive species were clearly resilient and can be found in a wide range of land use types, thus they may be more generalist than previously thought.

利用生态位模型估计豆娘和蜻蜓（昆虫纲：蜻蜓目）对土地利用变化的脆弱性的指数

摘要我们开发了一个主要发生在墨西哥的牙形石脆弱性指数，以评估土地利用变化。脆弱性被定义为a）物种习性和B）生态位模型的函数。指数验证是通过将其与植被覆盖变化率、每个物种的栖息地偏好以及物种对栖息地恶化的敏感性联系起来进行的。因此，最敏感的物种将出现在土地利用没有变化的地区。IVO值的范围从最大三个（即最敏感）到最小一个（即最小敏感）。正如其他研究所证明的那样，齿形石在保守和扰动的土地利用之间没有表现出明显的偏好。有趣的是，为数不多的敏感物种显然具有弹性，可以在各种土地利用类型中找到，因此它们可能比以前认为的更具普遍性。

期刊介绍： Aquatic Insects is an international journal publishing original research on the systematics, biology, and ecology of aquatic and semi-aquatic insects. The subject of the research is aquatic and semi-aquatic insects, comprising taxa of four primary orders, the Ephemeroptera, Odonata, Plecoptera, and Trichoptera but also aquatic and semi-aquatic families of Hemiptera, Coleoptera, and Diptera, as well as specific representatives of Hymenoptera , Lepidoptera, Mecoptera, Megaloptera , and Neuroptera that occur in lotic and lentic habitats during part of their life cycle. Studies on other aquatic Hexapoda (i.e., Collembola) will be only accepted if space permits. Papers on other aquatic Arthropoda (e.g., Crustacea) will not be considered, except for those closely related to aquatic and semi-aquatic insects (e.g., water mites as insect parasites). The topic of the research may include a wide range of biological fields. Taxonomic revisions and descriptions of individual species will be accepted especially if additional information is included on habitat preferences, species co-existing, behavior, phenology, collecting methods, etc., that are of general interest to an international readership. Descriptions based on single specimens are discouraged. Detailed studies on morphology, physiology, behavior, and phenology of aquatic insects in all stadia of their life cycle are welcome as well as the papers with molecular and phylogenetic analyses, especially if they discuss evolutionary processes of the biological, ecological, and faunistic formation of the group.
